ROOF STRUCTURE Filed Sept. 24, 1957 Patented `Feb. 22, -1938 "UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to roof coverings and has special reference to an interlocking sheet metal construction of roof covering. d

One importantv object of the invention is to provide a novel sheet metal roof construction, the elements of which may be preformed in a shop or factory and which may be interlocked upon the roof to be covered by simple manipulations and without the use of tools.

A second important object of the invention is to provide a novel device of this character Wherein the parts are held in position on the roof without the necessity of forming nail holes or other securing openings in the roof covering.

A third important object of the invention is to provide a novelroof covering of interlocking preformed sheets and novel securing clips therefor provided with means to engage interlocked portions of said roof covering, said clips being nailed to the roof with the nail heads beneath certain of the roof covering sheets.

A fourth important object of the invention is to provide a roof covering of the kind described and having novel combined snow guard and drainage means. v

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims. Y

In the accompanying 'drawing like characters of reference indicate like parts in the several views, andz- Figure 1 is a transverse section'of the eaves portion of a root showing the improved roof covering as applied thereto.

Figure 2 is a front elevation oi' the construction shown in Figure l.

Figure 3 is a fragmentary broken plan view of a portion of the novel roof covering and disclosing one of the clips used for securing the covering to the roof structure proper.

Figure 4 is an enlarged detail section on the line 4 4 of Figure 2.

In the embodiment of the invention herein disclosed there is shown in the drawing an inclined or sloping roof structure III. On this structure is shown the roof covering and securing means forming the subject of this invention. The roof. covering includes an eave plate II consisting of a metal sheet having its lower edge bent down to form a. depending ange I2 engaging the edge of the roof structure and extending along the upper edge of the plate II is a rebent portion (Cl. 10S-17) I3 extending downwardly over the adjacent portion of the sheet to form a downwardly opening channel on the upper side of the eave plate at its upper edge.

At I4 is a combined snow guard and drainage 5 plate. -This plate extends longitudinally of the roof and has a at body portion I5 preferably of less than half the width of the plate II. The plate I4 has a rebent upper edge portion I6 overlying the -body I5 so as to form a downwardly 10 open channel on the upper side of the snow guard plate and at the upper edge thereof. The lower edge portion of the plate I4 is curled upwardly in spiral formation as at I'I to form substantially more than one convolution whereby to provide an i5 upwardly inclined terminal portion I8.

At I9v is disclosed one of the clips -used herewith. This c lip comprises ra relatively narrow sheet metal strip having a body portion 20 having its lower end rebent downwardly as at 2| to form 20 an upwardly extending flange fitting in the channel of the-plate I4 which, in turn ts in the channel of the plate II. The clip I9 has a downwardly oiset upper end 2I which rests on the roof structure I0 and is there secured by a nail 22. 25 Thus the clip I9 secures the interlocked channel portions of plates II and I2 togetherand holds the upper edges of bth plates to the roof structure.

At 23 is a main roof covering sheet having a plane body portion iitting at its lower edge beneath the terminal portion I8-of the spiral I1 and extending upwardly of the roof in engagement at its upper edge with the rebent portion IIa of plate Ila and near its lower edge on the body of the 3.;

clip I9.

At its'upper edge this plate 23 is provided with a channel portion 2l corresponding in construction and function with the channel at the upper edge oi' plate Il. Thus the plate 23 covers the 40 clip and its securing nail.

A snow guard and drainage element or plate Ila is tted to plate 23 inthe same manner as that in which plates I4 and II are interlocked. A clip I9a is applied to the interlocked parts of plates 45 23 and Ila and secured as before.`A Over the clip Illa extends a plate 23a of the same dimensions and form as plate 23. This arrangement is continued throughout the whole roof.

It will now be seen that but four differently shaped elements are employed. 'Ihese elements are the eave sheet or plate II, combined snow guards and drainage sheets such as I4, the clips and the main covering sheets or plates such as 23.

It will be noted that when the parts are as-,Lus

sembled the spiral portions I1 act to prevent snow accumulated on the roof from sliding oif and that these spiral portions also serve to collect water from melting snow or rain water and cause it to be conducted laterally of the roof. Also there is no possibility of rain water being driven up beneath the roof by wind as often happens with shingle and'slate roofs.

There has been provided a simple and efficient roof covering of the kind described and for the purpose specified.

It is obvious that changes may be made in the form and construction of this roof covering without departing from the material principles of the invention. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is desired to include all forms which come within the scope of the appended claims.

What is claimed, iszx 1. A roof covering for inclined roofs including a cover sheet extending longitudinally of the roof, a snow guard member having a flat portion resting on the, upper part of said sheet, interlocking means formed on said sheet and snow guard at the upper edges thereof, a securing clip engaging said interlocking means and extending up the roof therefrom to have its upper end nailed to the roof, and a second cover sheet having its lower edge engagingly fitted under a portion of said snow guard and extending ,up the roof over said interlocking means and clip.
